GAS-LIG HTING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 689,866, dated December 31; 1901. Application filed April 4, 1901. Serial No. 54,322. (No model.)

To all whom it may concern:

Be it known that I, CARLOS FADER, a subj ect of the German Emperor, residing at Mendoza, Argentina, actually at Landau, Bavaria, Germany, have invented new and useful Improvements in Gas-Lighting Apparatus, (for which I have applied for a patent in Germany, dated December 13, 1900, application No. F. 13,602; in France, dated January 14, 1901, application No. 295,527; in Belgium, dated January 21, 1901, application No. 122,325, and in Great Britain, dated January 25, 1901, No. 1,770,) of which the following is a specification. I

The lighting every evening of municipal gas-lamps and the extinguishing of them at dawn at present necessitate a largenumber of lamplighters, which involves considerable expense. The removal of this inconvenience in public lighting systemshas alreadybeen repeatedly the object of inventions relating to automatic igniters, but so far without result, because they have not proved at all reliable. The introduction of electric street-lighting in many towns has rendered the employment of lamplighters superfiuous;but owing to the extreme cheapness of incandescent gas-lighting the illumination of the streets therewith has come again more and more into use, even where there already exist electric central stations. Consequently the need is again manifest of an automatic gas-igniting system applicable to each gas-lamp,

by means of a momentary augmentation or reduction of the pressure of the gas in the pipes.

The present invention, which is illustrated in the accompanying drawings in two forms of construction, is designed to fulfil the purpose of lighting the public gas-lamps simultaneously without further attention from the gas-works, or in case of domestic gas-lights from a pressure-regulator inserted in the gasmain in the house itself, and even of regulating the lights and of extinguishing some of them during the night and the rest of them simultaneously at dawn.

The gas-igniting apparatus is illustrated in section in the drawings and consists of a casing A, on whichis screweda ring B, provided with a curved support and boss 0. Between whereby it can be. lighted or extinguished from the gas-works the casing and the ring is fixed the edge of a flexible leather diaphragm D. On the casing A is a screw-threaded nipple e, onto which is screwed an ordinary burner, or, as shown in the drawings, aBunsen burner, F, for incandescent light. There is also on the casing a nipple g, into which is. screwed .either, as in Figure 1, a small gas-pipe H, on which is set arevoluble spongy platinum burner J,or else, as in Fig. 2, a small gas-pipe K, which opens into a conical pipe 1, attached to the Bunsen burner, so as to form within the latter an igniter-burner. In both figures, o is a cut-off and pressure-regulating rod which passes through the center of the diaphragm D and boss 0. This rod 0 is firmly connected with the diaphragm D by means of nuts and washers m. Between the diaphragm and the boss'is placed a counter-spring f, the tension of which can be adjusted by the regulatingscrew 2'. The ringj at the lower end of the valve rod 0' serves to control the ignition mechanism when the latter is under the day pressure. is in the shape of a slender regulating-cone g, which serves to regulate the flame of the burner F with varying gas-pressures.

In Fig. 1, r is a double valve-plug, which when the diaphragm D rises is moved to its seat sin the nozzle of the Bunsen burner and when it falls closes the passage in the valveseat 15. die a stop-ring on the valve-rod 0, which presses the lever h downward when the The upper end of the valve-rod 0 diaphragm is pressed down into its lowest position, owing to the maximum pressure of gas. In Fig. 1 the valve-rod v has at its upper end the valve-plug w, which closes the aperture of the valve-seat :20 by the pressure of the spring y. The lower end of this valverod 1) is provided with an adjustable stop a, on which rests the lever h. In Fig. 2 the valve-rod 0 has underneath the regulatingcone q a valve-plug e, which in the highest position of: the diaphragm D is moved to its seat sin the nozzle of the Bunsen burner. On this valve-rod 0 there is also a stop-ring u, on which the lever h rests. The valve-rod o is provided at the upper end with the valveplug to, which opens the aperture of, the valve-seat 00' when the diaphragm stands in its highest position. At the lower end of the valve-rod o are two set-nuts a Ct, between Which is placed the free end of the lever 71 and over which is the spring ;1 which engages, on the other hand, under the valveseat 50'. The gas-igniting apparatus, with the spongy platinum igniter, as shown in Fig. l, operates in the following manner: If the burner is out of operation-that is, when the gas-cock of the lamp is turned off-the diaphragm D is in its highest position, and the double valve-plug r on the valve-rod 0 closes the aperture of the valve seat 8. Consequently the valve-plug w on the valve-rod 1: also stands in its highest position and closes the aperture of the valve-seat After the turning on of the gas-cock, which when the lamp has once been put into operation always remains open, the diaphragm with the day pressure still remains in position I, as the counter-spring f, which is adjusted to this pressure, presses from below, and no gas passes to the burner F and the igniter J. As soon as the ordinary day pressure has been increased about a minute to the maximum pressure from the gas-works through the town mains the diaphragm is pressed down into the lowest position III. Consequently the valve-rod o sinks and closes the aperture t by means of the double valve-plug 1'. Meanwhile the stop it has pressed the lever 7L and the valve-rod r downward, whereby the valveplug 10 opens the passage in the valve-seat:r, so that gas passes to the igniter and ignites, owing to the catalytic properties of the spongy platinum. After this has taken place the maximum pressure is adjusted from the gasworks to evening pressure, in consequence of which the diaphragm again rises into the position IV and lifts the valve-rod 0, which opens the aperture 25, and gas passes through this and the still open passage :2: to the burner F and ignites at the ignition-flame. Immediately afterward the lever h is released and the spring to presses the valve-plug on the valve-seatcc. Consequently the passage of the gas is cut off and the ignition-flame is extinguished. To extinguish the lamps at dawn, the gas-pressure is reduced to the day pressure from the gas-works. Consequently the diaphragm D rises into the highest position I and the double valve-plug r closes the aperture of the valve-seat s, and therefore cuts oil the gas-supply to the burner I whereupon the light is extinguished. The case of this invention is therefore the arrangement of the valve-cones z and 0' and of placing the slight regulating-cone q into the passage of nozzle of the Bunsen burner. This cone q diminishes more or less the opening of the valve-seats for allowing more or less the access of the gas to the Bunsen burner F or closing it, whereby the regulating-cone only regulates the quantity of gas at different gaspressures.

The gas-igniter, as illustrated in Fig. 2, operates as follows: When the burner is out of operation-that is, when the gas-cock of the lamp is turned oifand it is put in operation for the first time, the diaphragm D is in its highest position I, as shown in the drawings. The valve-rod 0 is also in its highest position, the valve-plug being moved to its seat .9 in the nozzle of the Bunsen burner. Accordingly the lever h is also in its highest position on the stop a and the valve-rod 1; with the plug '10, which thus opens the aperture in the valve-seat as. On opening the gascock, which subsequently remains always open, the diaphragm with day pressure still remains in the same position I,as the counterspringf, which is adjusted to this pressure, presses from below. Gas now flows immediately through the passage of the valve-seat w and through the tube to the small Bunsen igniter I, which is now ignited once and forall. As soon as the ordinary day pressure has been increased from the gas-works to evening pressure the diaphragm D is forced down to po sition IV. The valve-rod 0 thereby sinks, and the valve-plugs opens the passage inthe valve-seat s and allows the gas to pass to the main burner F, which ignites at the gas-ignition flame of the small by-pass burner l. Meanwhile the stop it has released the lever 71 whereupon the spring 7 presses down the valve-rod nwith the plug 20, which closes the aperture :r, so that the ignition-flame goes out. To extinguish the flame of the lamp,

the morningpressure (from midnightto dawn) is adjusted from the gas-works to day pressure again. Hereupon the diaphragm D rises again to its highest position, whereby the stop a raises the lever,and consequently the valverod r, with the valve-plug w, so that the passage in the valve-seat (6' is free, and gas passes to the small by-pass burner Z and ignites at the still burning main flame F, whereupon the latter goes out as the valve-plug z closes the passage in the valve-seat s.

The slender regulating-cone (1 over the valve-plugs r flame of the main Bunsen burner F to the gas-pressure at the time, which is effected by the diaphragm D correspondingly rising or falling, according as the gas-pressure is reduced or increased during the night to the day and maximum evening pressure, and the passage for thegas through the valve-seat s is enlarged or reduced by the cone rising or sinking.

In case a number of lamps are to be ex tinguished during the night the springfis adjusted in the respective apparatuses in such a manner that they are extinguished at a pressure between the maximum evening pressure and the day pressure, which is adjusted at a given time from the gas-works.

The gas-igniting apparatuses can be adapted for receiving several burners to be fitted with valves which are operated by the same diaphragm by transmitting the up-and-down motion thereof to the respective valves. The

device of the diaphragm D, with its shutting off and regulating cone,could also be arranged so that instead of a lever h effecting the igand serves to regulate theininating pressure,
